Exchange Rate Pass-Through into Romanian Price Indices: A VAR Approach

This paper investigates the exchange rate pass-through (ERPT) into import prices, producer prices and several different measures of consumer prices indices for Romanian economy. In order to determine the size, describe the dynamics and identify the asymmetries in ERPT the paper employs an array of econometric methods belonging to the VAR family. The methods range from RVARS (on different price indices and/or on a rolling window), Sign-restriction VARs (also using different consumer inflation measures), MS-VAR, TAR and SETAR, the last three methods being naturally equipped to capture various types of asymmetries. The results point to an almost complete passthrough into import prices and incomplete pass-through into producer and consumer prices. In all cases except import prices the ERPT displays a decline in magnitude over the analysed time interval. The paper also finds important asymmetries with respect to sign and size of the exchange rate, size of inflation and time period.exchange rate, pass-through, import prices, producer prices, consumer prices, vector autoregression, sign-restriction

Asymmetries In The Exchange Rate Pass-Through Into Romanian Price Indices

The article examines the asymmetries of the exchange rate pass-through (ERPT) into import, producer and consumer price indices for the Romanian economy. Using three econometric methods naturally equipped to capture various types of asymmetries (MS-VAR, TAR and SETAR), important asymmetries with respect to sign and size of the exchange rate, size of inflation and time period have been detected.exchange rate, pass-through, import prices, producer prices, consumer prices, vector autoregression, asymmetries, MS-VAR, TAR, SETAR

3D Modeling for Digital Preservation of Romanian Heritage Monuments

AbstractPrecise documentation of cultural heritage monuments status is essential for its protection and scientific studies. The digital preservation of cultural heritage monuments is a specially challenging application of 3D modelling. Cultural heritage objects and sites greatly differ from each other and a maximized fidelity of the 3D model is a core requirement.Terrestrial laser scanning is a technology that in recent years has become increasingly popular for documentation which provides very dense 3D points on an object surface with high accuracy.Moreover the resulting 3D models can be used for digital documentation as well as to perform different analysis such as measurements, conservation monitoring, feature extractions and possibly virtual restoration.Thispaper presents the3D modelling oftwoof the most importantheritage monumentsinRomania: the rock sculpture ofDecebaluson the Danube,Orsovaand the Sphinxfrom Bucegi Mountains, without any loss of details or accuracy

A Site Evaluation Campaign for a Ground Based Atmospheric Cherenkov Telescope in Romania

Around the world, several scientific projects share the interest of a global network of small Cherenkov telescopes for monitoring observations of the brightest blazars - the DWARF network. A small, ground based, imaging atmospheric Cherenkov telescope of last generation is intended to be installed and operated in Romania as a component of the DWARF network. To prepare the construction of the observatory, two support projects have been initiated. Within the framework of these projects, we have assessed a number of possible sites where to settle the observatory. In this paper we submit a brief report on the general characteristics of the best four sites selected after the local infrastructure, the nearby facilities and the social impact criteria have been applied.Comment: 6 pages, 5 Postscript figure

The use of computational fluid dynamics applications to various flow problems

To deal with any such applications, it is a must to understand the basic form and nature of the governing equations of fluid dynamics. It is imperious to fully understand the basic of numerical discretization that can be applied in equations. This paper aims to present some CFD tools that are the starting point in solving problems related to the field of fluid dynamics. During this work, we will note that anyone CFD technique will not be appropriate for all problems and the diverse mathematical nature of partial differential equations will ensure that some algorithms will best work for hyperbolic equations and others will do best for elliptic equations. In addition, this paper examines precisely how CFD techniques can be used to solve various flow problems. In other words, CFD applications requires the simultaneous knowledge of some major aspects, such as the governing flow equations and their mathematical behavior, aspects of numerical discretization of partial differential equations, also known as finite differences or of integral equations, known as finite volumes. Computational fluid dynamics has a major impact on airplane design and soon to be a critical technology for aerodynamic design with the purpose to enhance the design process for any machine that deals with fluid flow

Looking beyond appearances: a multi-analytical approach on the prehistoric clay weights

AbstractIn this paper we analyzed a batch of 64 clay weights from three archaeological sites located in Romania (Gumelniţa, Măgura-Jilava, and Sultana) that belong to Kodjadermen-Gumelniţa-Karanovo VI cultural complex (4600–3900 cal. BC). Our approach includes an interdisciplinary investigation based on technological analysis, experimental archaeology, and X-ray CT scans coupled with statistical analysis. This investigation has a high potential to reveal relevant information regarding the technological background (e.g., inclusion, voids, temper, etc.), manufacturing stages (e.g., modeling, shaping, kneading, etc.), or transformation processes (e.g., drying and firing vs. weight and size modification) in order to identify, explain and understand thechaîne operatoirefor this type of artefacts. Moreover, correlation of the results with the experimental archaeology could offer an integrative interpretation about the material culture of past humans and its multiple meanings, but also critical information about the multiple dimensions of manufacture for these objects (e.g., time, effort, physical–chemical processes, etc.). The multi-analytical approach proposed here also includes a comparative study of technological aspects of these clay weights across the three archaeological sites investigated, as well as the experimental replicas

Between Object and Subject

The current paper aims to reveal the potential of combining multiple approaches (techno-functional analysis, experimental archaeology, and X-ray Computed Tomography) when it comes to studying unique earthenware artefacts, such as the prehistoric human-shaped pot discovered within the tell settlement from Sultana-Malu Rosu (Romania), that belongs to the Kodjadermen-Gumelnita-Karanovo VI civilization (KGK VI) which thrived during the 5th millennium BC. This human-shaped pot, also known as ‘The Goddess of Sultana’, is an emblematic artefact that fascinates with its shape, gestures, and decoration. It was apparently made from a standard clay paste recipe and using basic forming techniques, with little care for the internal surface. This vessel also has several hidden cracks and some manipulation traces on its backside. In order to explore its relevance, our approach to this particular human-shaped pot included the use of archaeological data in correlation with other techniques in order to decipher the manufacturing process for such vessels, the possible way of using them, but also the meanings that they might have had for past human communities

Measurement of the mass difference m(D-s(+))-m(D+) at CDF II

We present a measurement of the mass difference m(D-s(+))-m(D+), where both the D-s(+) and D+ are reconstructed in the phipi(+) decay channel. This measurement uses 11.6 pb(-1) of data collected by CDF II using the new displaced-track trigger. The mass difference is found to be m(D-s(+))-m(D+)=99.41+/-0.38(stat)+/-0.21(syst) MeV/c(2)
